Alimony & Spousal Maintenance Calculator

Get a jurisdiction-specific guideline, statutory limit or financial-needs scenario, with every step explained. This is not a prediction of a court award.

1 Choose the applicable law

Select the country and legal region where your case would be handled. Local rules vary; your home address does not always decide jurisdiction.

2 Relationship and children

Children's ages and care arrangements may affect earning capacity, costs, legal guidelines and potential support duration. There is no universal payment added for each child.

Enter total years living together; jurisdiction-specific questions may ask separately for years legally married.
Children and care arrangements

Add children who depend on either parent, including adult children with ongoing support needs. Leave blank if there are none.

3 Monthly finances (AUD)

Use current or realistically expected monthly amounts. Income below is after tax. Keep child support separate. Never include the spousal maintenance amount you are trying to estimate.

Potential recipient
Housing, food, transport, bills; don't double-count childcare below.
Only costs not already included in living expenses.
Only evidenced extra costs not included above: housing, therapy, transport or ongoing needs. Do not add a speculative entitlement.
Shown as context, not automatically treated as monthly income.
Potential payer
Exclude anything already in living expenses.
Do not repeat child support or living costs.
Important: These monthly figures are a budget baseline, not a legal definition of income. Support calculations in some jurisdictions require separate annual gross or statutory-adjusted income figures.

4 Applicable legal guideline inputs

Any additional questions needed for the selected country's supported formula will appear here. Where no defensible general formula exists, we'll show a clearly labelled budget-based support scenario instead.

Local calculations can require annual GROSS income, statutory NET income or filing details in addition to the monthly budget above. Enter these only if you know the correct definitions.
